Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning device. Background Art

[0002] A sweeping robot is a device used to clean up small garbage and dust in the home. It is deeply loved by consumers because of its functions such as self-cleaning, automatic garbage dumping, and automatic recharging.

[0003] Robot vacuums typically feature side sweepers and center sweepers. The side sweepers can clean dust and small debris in blind spots, while the center sweeper's suction port sweeps the floor's debris compartment toward the robot's center, allowing the center sweeper's suction port to remove hair. However, existing robot vacuums often get tangled with hair on the side sweepers during cleaning operations, and the hair easily forms a tangled mass on the side sweepers, negatively impacting the side sweeper's cleaning performance. Furthermore, when the center sweeper's suction port removes hair, the tangled hair easily becomes tangled on the center sweeper, reducing the robot's cleaning efficiency. Utility Model Content

[0004] The main purpose of the present application is to provide a cleaning device to solve the problem in the prior art that hair entangled on the side of the sweeping robot easily forms clumps, resulting in low cleaning efficiency of the sweeping robot.

[0013] Furthermore, the combing portion includes comb teeth, and the comb teeth include a plurality of racks, and the plurality of racks are arranged at intervals at the bottom of the main body, and each of the racks is protruded from the bottom surface of the main body.

[0014] Furthermore, when the side sweeping assembly is in operation, the cleaning arm forms a circular motion trajectory with the geometric center of the side sweeping assembly as the center;

[0015] The extending direction of each rack is tangent to the extending direction of the circular motion trajectory; or,

[0016] The extending direction of each rack is the same as the extending direction of the circular motion trajectory.

[0017] Furthermore, the cross-sectional area of each rack gradually decreases.

[0018] Furthermore, a bottom plate and a middle sweep cover plate are provided on the main body, and both the bottom plate and the middle sweep cover plate are provided at the bottom of the main body, and the combing part is provided on the bottom plate or the middle sweep cover plate.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0038] As mentioned in the background, existing robot vacuums tend to get tangled with hair while sweeping, and the hair can clump together on the side sweepers, affecting the cleaning effect of the side sweepers. Furthermore, when the suction port of the middle sweeper sucks away the hair, the clumps of hair can easily become tangled on the middle sweeper, reducing the cleaning efficiency of the robot vacuum. To address this issue, the inventors of this application have designed a novel cleaning device that can address the problem of hair tangling easily and clumping together on the side sweepers of existing robot vacuums, resulting in low cleaning efficiency. The cleaning device of this application will be described in detail below with reference to the accompanying drawings.

[0039] See also Figures 1 to 6 As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a main body 10 , a side sweeping assembly 20 and a combing part 30 .

[0040] Specifically, the side sweeping assembly 20 is rotatably disposed at the bottom of the main body 10, and the side sweeping assembly 20 includes at least one cleaning arm 21; the combing portion 30 is disposed at the bottom of the main body 10 and is located within the rotation range of the side sweeping assembly 20; wherein, when the side sweeping assembly 20 rotates, the combing portion 30 contacts the cleaning arm 21 to at least comb the hair wrapped around the cleaning arm 21.

[0041] In this embodiment, the rotation of the side sweep assembly 20 can drive the cleaning arm 21 to rotate. When the cleaning arm 21 rotates, it can clean the edges of the space, thereby sweeping dust and garbage into the cleaning range of the middle sweep 12 of the cleaning device. At the same time, because the combing portion 30 in this embodiment is arranged at the bottom of the main body 10 and is located within the rotation range of the side sweep assembly 20, the cleaning arm 21 will come into contact with the combing portion 30 during the rotation of the cleaning arm 21. When hair is entangled on the cleaning arm 21, the arrangement of the combing portion 30 can comb out the hair entangled on the cleaning arm 21, preventing the hair from tangling into a ball during the rotation of the cleaning arm 21, thereby ensuring the cleaning effect of the side sweep assembly 20. At the same time, the hair combed out by the combing portion 30 will be sucked away by the suction port of the middle sweep 12, thereby preventing the balled hair from entangled on the middle sweep 12, effectively improving the cleaning efficiency of the cleaning device.

[0042] Optionally, the cleaning arm 21 in this embodiment can be provided as one, or as two or more. Figure 6 FIG. 5 shows a case where three cleaning arms 21 are provided.

[0043] Furthermore, the combing portion 30 in this embodiment includes comb teeth 31 or a brush (not shown in the drawings).

[0044] Specifically, this embodiment provides comb teeth 31 or a brush at the bottom of the main body 10, and the comb teeth 31 or the brush are located within the cleaning range of the cleaning arm 21. In this way, during the rotation of the cleaning arm 21, it can be ensured that at least part of the comb teeth 31 or the brush is in contact with the cleaning arm 21 and inserted into the inside of the cleaning arm 21. When hair is entangled on the cleaning arm 21, the comb teeth 31 or the brush will comb the hair apart to prevent the hair from gradually entangled into a ball as the cleaning arm 21 rotates, thereby improving the cleaning effect of the side sweep assembly 20, and the hair will leave the cleaning arm 21 and be sucked away by the suction port of the middle sweep 12 under the combing of the comb teeth 31 or the brush, effectively improving the cleaning efficiency of the cleaning device.

[0045] Further, see Figure 3 as well as Figure 5As shown, when the side sweeper assembly 20 of this embodiment is in operation, the cleaning arm 21 forms a circular motion trajectory 211 with the geometric center of the side sweeper assembly 20 as the center. The combing portion 30 includes comb teeth 31, and the comb teeth 31 extend in the same direction as the circular motion trajectory 211. It should be noted that the "geometric center of the side sweeper assembly 20" in this embodiment refers to the geometric center of the projection surface of the side sweeper assembly 20 within the projection along the thickness direction of the side sweeper assembly 20.

[0046] Specifically, because the cleaning arm 21 in this embodiment performs a circular motion with the geometric center of the side sweep assembly 20 as a circle, this ensures that the cleaning arm 21 can evenly cover the cleaning area, thereby improving the cleaning effect of the side sweep assembly 20 to a certain extent. At the same time, because the extension direction of the comb teeth 31 in this embodiment is the same as the extension direction of the circular motion trajectory 211, the contact area between the comb teeth 31 and the cleaning arm 21 is increased. When hair is entangled on the cleaning arm 21, the comb teeth 31 can fully contact the cleaning arm 21, thereby more effectively combing out and combing out the hair entangled on the cleaning arm 21, avoiding the hair entangled with the cleaning arm 21 and clumping on the cleaning arm 21, which affects the cleaning effect of the cleaning arm 21. At the same time, it facilitates the suction port of the middle sweep 12 to suck away the combed hair, thereby improving the cleaning efficiency of the cleaning device.

[0047] Further, see Figure 3 As shown, the combing portion 30 in this embodiment includes comb teeth 31, and the comb teeth 31 include multiple racks 311. The multiple racks 311 are spaced apart and arranged at the bottom of the main body 10, and each rack 311 is protruded from the bottom surface of the main body 10. It is understood that the racks 311 in this embodiment can be provided as two, three, or more than three, and this application does not make specific limitations here. As long as other variations based on the concept of this application are within the scope of protection of this application, they are all within the scope of protection of this application.

[0048] Specifically, the arrangement of the multiple racks 311 can comb away hair entangled on the cleaning arm 21, allowing the hair to easily detach from the cleaning arm 21 and be sucked away by the middle sweep 12, thereby ensuring the cleaning effect of the side sweep assembly 20 and the middle sweep 12 during subsequent operation. The multiple racks 311 are spaced apart so that the combed hair can pass smoothly between two adjacent racks 311 without being trapped by the comb teeth 31 or entangled between the racks 311. This effectively prevents clogging of the comb teeth 31, speeds up the combing process, and effectively improves cleaning efficiency. At the same time, each rack 311 in this embodiment is protruding from the bottom surface of the main body 10. This arrangement increases the contact area between each rack 311 and the cleaning arm 21, effectively preventing hair from remaining in certain areas of the cleaning arm 21 due to insufficient contact with the racks 311, and to a certain extent improves the combing effect of the comb teeth 31 on the cleaning arm 21.

[0049] Further, see Figure 3 as well as Figure 5 As shown, when the side sweep assembly 20 of this embodiment is in operation, the cleaning arm 21 forms a circular motion trajectory 211 with the geometric center of the side sweep assembly 20 as the center. The extension direction of each rack 311 is tangential to the extension direction of the circular motion trajectory 211. This arrangement increases the contact area between each rack 311 and the cleaning arm 21, ensuring that each rack 311 is in contact with the cleaning arm 21. This allows hair to be combed away during the rotation of the cleaning arm 21 without causing hair to become tangled on the cleaning arm 21, effectively improving the cleaning performance of the side sweep assembly 20 and the cleaning device as a whole.

[0050] Further, see Figure 4 As shown, when the side sweeping assembly 20 in this embodiment is working, the cleaning arm 21 forms a circular motion track 211 with the geometric center of the side sweeping assembly 20 as the center. The extending direction of each rack 311 is the same as the extending direction of the circular motion track 211.

[0051] Specifically, on the basis that the aforementioned rack 311 is tangent to the circular motion trajectory 211, the extension direction of each rack 311 in this embodiment is the same as the extension direction of the circular motion trajectory 211. In this way, it can be ensured that when the cleaning arm 21 rotates to the comb teeth 31, each rack 311 can always maintain contact with the cleaning arm 21, which is beneficial for combing the hair entangled on the cleaning arm 21, further improving the combing effect of the comb teeth 31 on the cleaning arm 21, and effectively ensuring the cleaning efficiency of the cleaning device.

[0052] Furthermore, the cross-sectional area of each rack 311 in this embodiment (i.e., the area of the cross section obtained by cutting the rack 311 perpendicular to its extension) gradually decreases. This arrangement not only ensures that each rack 311 can penetrate deeply into the cleaning arm 21, increasing the contact area between each rack 311 and the cleaning arm 21 to facilitate combing hair off the cleaning arm 21, but also reduces the overall weight of the combing unit 30, lowering its manufacturing cost. It will be appreciated that, since each rack 311 in this embodiment is protruding from the bottom surface of the main body 10, each rack 311 extends away from the bottom surface of the main body 10.

[0053] Further, see Figure 2As shown, the main body 10 in this embodiment is provided with a base plate 11 and a middle sweep cover plate 121. Both the base plate 11 and the middle sweep cover plate 121 are disposed at the bottom of the main body 10. A combing portion 30 is disposed on the base plate 11 or the middle sweep cover plate 121. Specifically, the provision of the combing portion 30 on the base plate 11 or the middle sweep cover plate 121 ensures that the combing portion 30 comes into contact with the cleaning arm 21, thereby enabling the combing portion 30 to comb the hair on the cleaning arm 21. Furthermore, whether the combing portion 30 is provided on the base plate 11 or the middle sweep cover plate 121, as long as the combing portion 30 is within the rotation range of the cleaning arm 21, the contact area between the combing portion 30 and the cleaning arm 21 is increased, thereby improving the combing effect of the combing portion 30 on the hair, thereby preventing hair from becoming entangled in the cleaning arm 21 and affecting the cleaning effect of the cleaning arm 21.

[0054] Furthermore, the combing portion 30 in this embodiment is integrally injection-molded with the main body 10 or detachably mounted on the bottom of the main body 10. Specifically, when the combing portion 30 and the main body 10 are integrally injection-molded, the overall structure is stable and reliable, facilitating contact between the combing portion 30 and the cleaning arm 21 of the side sweep assembly 20 and combing hair entangled therein. When the combing portion 30 in this embodiment is detachably attached to the bottom of the main body 10, the combing portion 30 and the main body 10 can be connected by screwing, welding, or snapping, resulting in a simple structure and easy installation and removal of the combing portion 30.

[0055] Further, see Figure 6 As shown, a motor (not shown in the drawings) is provided on the main body 10 in this embodiment, and the side sweeping assembly 20 further includes a side sweeping body 22 and a support arm 23. The side sweeping body 22 is rotatably connected to the motor; the support arm 23 includes at least one, and the first end of the support arm 23 is connected to the side sweeping body 22; wherein the support arm 23 is provided in a one-to-one correspondence with the cleaning arm 21, the first end of the cleaning arm 21 is connected to the second end of the support arm 23, and the cleaning arm 21 and the support arm 23 have different extension directions. It can be understood that the support arm 23 in this embodiment can be set as one, or can be set as two or more. Figure 6 FIG. 5 shows a case where three support arms 23 are provided.

[0056] Specifically, when the side sweep assembly 20 of this embodiment is installed on a cleaning device, such as a sweeping robot or a cleaning base station, a motor is connected to the side sweep body 22 to drive the side sweep body 22 to rotate, thereby driving the support arm 23 and the cleaning arm 21 to rotate synchronously. When the cleaning arm 21 rotates, it can clean the edges of the space, thereby sweeping dust and garbage into the cleaning range of the middle sweep 12 of the cleaning device. At the same time, because the support arm 23 is provided between the cleaning arm 21 and the side sweep body 22 of this embodiment, when hair is entangled on the cleaning arm 21, the provision of the support arm 23 can extend the distance between the cleaning arm 21 and the side sweep body 22, preventing the hair on the cleaning arm 21 from directly contacting the side sweep body 22 and being entangled on the side sweep body 22 and the rotating shaft of the motor. In addition, since the cleaning arm 21 and the support arm 23 in this embodiment have different extension directions, when the hair is entangled on the cleaning arm 21, the support arm 23 can act as a barrier between the cleaning arm 21 and the side sweeper body 22, thereby making it difficult for the hair on the cleaning arm 21 to be entangled on the support arm 23, thereby preventing the hair from contacting the side sweeper body 22 and being entangled on the side sweeper body 22 and the rotating shaft of the motor.

[0057] Combine Figure 6 As shown, the side sweeping body 22 in this embodiment is generally arranged in a cylindrical block structure, and the cylindrical block can be a cylindrical block, a prismatic block or other special-shaped cylindrical blocks, etc. Figure 6 1 and 2 show the situation when the side sweeping body 22 is arranged as a cylindrical block structure. When actually connected, the support arm 23 is connected to the outer edge of the cylindrical block.

[0058] Specifically, to improve the structural strength and service life of the side sweep assembly 20 in this embodiment, the support arm 23 and the side sweep body 22 are integrally formed by injection molding, resulting in a stable and reliable structure. Of course, in other embodiments of the present application, the support arm 23 and the side sweep body 22 can also be connected by screwing, welding, or clamping. As long as these other variations are within the scope of protection of this application, they are all within the scope of protection of this application.

[0059] Further, see Figure 2 As shown, a bottom plate 11 is provided on the main body 10 in this embodiment. The bottom plate 11 has a recessed portion 111 . The side sweeping assembly 20 is rotatably installed in the recessed portion 111 , and at least a portion of the combing portion 30 is located in the recessed portion 111 .

[0060] Specifically, this embodiment, by providing a recessed portion on the bottom plate, can accommodate other functional components such as the combing portion 30 within a limited space, and is conducive to the arrangement of other functional components outside the recessed portion, effectively improving the space utilization rate of the bottom plate. At the same time, since at least part of the combing portion 30 in this embodiment is located in the recessed portion 111, when hair is wrapped around the cleaning arm 21, the arrangement of the combing portion 30 can comb out the hair wrapped around the cleaning arm 21, preventing the hair from being tangled into a ball during the rotation of the cleaning arm 21, thereby ensuring the cleaning effect of the side sweeping assembly 20. It can be understood that "at least part of the combing portion 30 is located in the recessed portion 111" in this embodiment can mean that part of the combing portion 30 is located in the recessed portion 111 and the other part of the combing portion 30 is located outside the recessed portion 111, or all of the combing portion 30 is located in the recessed portion 111. The recessed portion 111 in this embodiment can also mean that all of the combing portion 30 is located in the recessed portion 111. Figure 3 and attached Figure 4 FIG. 3 shows a situation where a portion of the combing portion 30 is located in the recessed portion 111 and another portion of the combing portion 30 is located outside the recessed portion 111 .

[0061] In combination with the above embodiments, it can be known that the present application provides a combing portion 30 within the rotation range of the side sweep assembly 20. When hair is entangled on the cleaning arm 21, as the cleaning arm 21 rotates, the combing portion 30 will comb out the hair on the cleaning arm 21 to prevent the hair from being entangled into a ball, making it easier for the hair to detach from the cleaning arm 21 and be sucked away by the suction port of the middle sweep 12, effectively ensuring the cleaning effect of the side sweep assembly 20 and improving the cleaning efficiency of the cleaning device.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0063] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0064] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
